Jan, does that mean if you were sailing on a Regent cruise that you would tip for room service even though the literature specifically says it is an all-inclusive, no tipping cruise?

We have breafast room service almost every morning when we sail Regent and I never tip. The room service waiters are only doing their job - delivering room service. Like others have said here, Regent pays their staff more due to the "no-tipping" policy. A contribution to the crew fund to reward good service is much fairer in that it rewards all the personnel who have helped you during the cruise.
